[PATCH net-next 0/2] hv_netvsc: Eliminate memory allocation in the send path

["K. Y. Srinivasan" <kys@microsoft.com>]

The network protocol used to communicate with the host is the remote ndis (rndis)
protocol. We need to decorate each outgoing packet with a rndis header and
additional rndis state (rndis per-packet state). To manage this state, we
currently allocate memory in the transmit path. Eliminate this allocation by
requesting additional head room in the skb.


K. Y. Srinivasan (2):
  hyperv: Cleanup the test for freeing skb when we use sendbuf
    mechanism
  hyperv: Eliminate memory allocation in the packet send path
